Is the father’s haram earning halal for his child?
If it is halal, up to what age?

Dear Brother / Sister,

If the father’s earning is haram, his children can meet their needs from his earning as a necessity until they find a way of making their living. If they have a relative whose earning is halal, he can meet their needs; or, if they earn halal money, they will stop using their father’s haram earning.
